Ferner CAR-'ROOF'.

SPLEQFIGAEION forming part of Letters Patent No. 696,976, dated April 8, 1902.

Application filed December 23, 190]. Serial No. 87,004. (No model To al?, whom t may concern:

Be it known that I, CURTIS M. JENNINGS, a citizen of the United States, residing at St. Louis, iu the State of Missouri, have invented a new and useful Improvement in Oar-Roofs, of which the following is a specification.

My invention relates to a metallic car-roof for freight-cars, and has for its object to provide a rigid and durable car-roof of simple `construction Without the use of the upper purlins, upper ridge-pole, roof-boards, and fascias ordinarily appertaining to this class of roof.

The invention consists in features of novelty, as hereinafter described and claimed, reference being had. to the accompanying drawings, forming part of this specification, Whereon Figure l is a top plan of my improved metallic car-roof broken away; Fig. 2, a vertical transverse section, to enlarged scale, through the roof, broken away on line 2 2 in Fig. l; Fig. 3, a cross-section, to enlarged scale, through one of the carlines and adjacent roof-sheets, broken away on line 3 3 in Figs. l and 2; and Fig. 4, an end view of the carline and adjacent roof-sheets at their junction to the` side of the car, seen in side elevation broken away.

Like letters and numerals of reference denote like parts in all the gures.

In my improved metallic car-roof, ct represents the carlines; t, the roof-sheets; c, the lower purlins, and c' a middle tie-plate correspondi'n gto the purlins c and substituted for the ordinary ridge-pole of a car-roof. Each car-line o. is composed of iron, steel, or other suitable material and is preferably channelshaped in cross-section, having the bottom fiat portion orbase 1 andthetwo upwardly-projecting side flanges 2, which are directed outward at the top 8 and formed thereat with a depending ange 4, which is opposite to and parallel, or thereabout, With the side flanges 2 at a suitable distance therefrom. The roof-sheets b, which are preferably flat, extend between the carlines a and are formed, respectively, at each side with an upwardly-projecting flange 5, which is adapted to engage between the side flange 2 and the outer depending flange 4 of the corresponding carline d, adjacent thereto, the fianges 2 and 4, with their top connecting portions 3, forming housings to the fianges 5 of the roof-sheets b, and thereby excluding rain and dust from the car.

The carlines a, and roof-sheets b,which span and overhang the sides d of theV car, are of equal length and preferably in one piece, respectively, from end to end, the sides d of the car having outwardly-projecting top fianges 6 extending their entire length, to which the overhanging end portions of the carlines a and roof-sheets b are -firmly secured by rivets '7, which in the case of the carlines a pass through the base l and flanges 6, as shown. To the inner face of each side CZ at the top is preferably fixed an angle-plate e, having its upper projecting leg 8 flush with the fiange 6, and to this leg 8 the carlines a and roofsheets b are fixed by rivets 9. Each end' of the car (not shown) is also preferably proi vided With an overhanging top fiange and inside angle-plate similar to the flange 6 and plate e of the sides d.

The lower purlins c and middle tie-plate o'` may be of flat bar or other suitably-shaped irons and are fixed to the carlines a and roofsheet-s b on their under side by rivets 1G, as shown.

The running-board f is supported on bearers g, made of pressed steel, malleable castiron, or other suitable material in any desired form and fixed at the base to the roof-sheets b at each side of the roof-ridge by rivets l1 or otherwise, as found most suitable.

By the special form of carline a above described the j oint-strips or roof-rafters andthe deep Wooden carlines or rafters Within the car, as also the upper purlins and upper ridgepole and fascias, are dispensed with and the construction of the roof greatly simplified; also, by making the carlines ct in one piece, respectively, from side to side of the car and attaching them at the eaves to the overhanging fianges 6 and inside plates e of the sides d of the car the roof is rendered more rigid and durable and adds greater strength to the car than by the ordinary construction.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. I n a car-roof, the combination with the sides of the car having respectively an loutwardly-proj ectin g top flange,of a carline made in one piece spanning the said sides, the said IOO vhaving a flat base bearing upon the said plate,

earline having a flat base bearing upon the said flanges, and having two upwardly-projecting side flanges directed outward at the top and formed thereat respectively with a depending flange, a roof-sheet having a side flange adapted to engage between the said side flange and depending flange ofthe earline, and means for fixing the cai'line and roof-sheet to .thev said top flanges of the oar, substantially as described.

2. In a car-roof, the combination with the sides of the oai' having respectively an inside top angle-plate, of a earline made in one' pieee spanning the said sides, the said earline and having two upwardly-projecting side 'flanges directed outward' at the ltop and formed thereat respeetivelywith a depending flange, a roof-sheet having a sideflange adapted to engage between the said side flange and depending flange of the 'carline, and means CURTIS M. JENNINGS.
